Internal roller swaging device and method

A swaging device comprising:

• a roller swaging assembly configured to receive a fitting with an inserted tube, said roller swaging assembly including expandable swage rollers;
• a mandrel extending through said roller swaging assembly;
• a forming assembly including said mandrel and said expandable swage rollers;
• an axial movement of said mandrel in combination with said swage rollers facilitating a swaging of said received tube;
• a relative axial position of said mandrel to the roller swaging assembly being measured;
• and
• said measured relative axial position being used to configure further interaction between said mandrel and said roller swaging assembly and being used to calculate an actual wall thickness of the tube based on the measurement of the axial position, and calculate a quality of a swage based on the calculated actual wall thickness.

A device for swaging a tube and a fitting to one another, the device comprising:

• a drive mechanism including a drive motor;
• a mandrel rotated by said drive mechanism to swage the tube and fitting to one another;
• a drive head disposed between the drive mechanism and the mandrel;
• a position sensor for measuring an axial position of said mandrel;
• and
• a controller configured to terminate swaging in response to receiving a signal generated by a torque sensor;
• wherein the torque sensor is configured to generate the signal indicative of a torque rise associated with a flow of tube material consisting of flow in an axial direction along the fitting.
